42108 mods and improvements

Recommended Posts

Thanks for the kind words, The modded model I shared has a lot of floating parts so wouldn't be possible to build , I have just this minute finished building the full original digital model in LDCAD (the file I shared above was based on somebodys reverse engineered STUD.IO (studio) digital model.

If you are able to wait a little, I can try to add my mods to the full LDCAD file thus I would therefore be able to give a final addon parts list (some parts that are removed from the original will be used for the mod).

As for the drivetrain, If I made it floating then the drive motor would also need to move up and down as well as the driveshaft and the wheel axles. So instead I am using pivoting axles with suspention. I plan to utilize the 3x3 technic biscuit joints and 7x11 frames as a wrapper for the motors and mechanisms, while being structural to other 'frame exteral' things too.

Regards, Snipe

sorry for the follow-up but i have a question regarding the differentials:

I've loaded the model in LDCad and notice that in place of the 2-part differential there is a red 28 cog wheel 46372 and 2 pieces 98585.

Is this an error on my part or a placeholder ? (i am experienced with CAD Programs in genral but still learning LDCad)

Would this also work with the 62821b differential actually ? (i assume then the 12-cog wheel 32270 would need to be changed to 32269 20 cog but that would change the gear relation then)

Oh yeah I forgot to mention, its just a representation of the new differential that are in set 42109. The cog in that set has a half pin hole but is not in LDCAD yet. the two gray technic discs are the differential case.

Yes the old 62821b differentials should work assuming you add 3 inner bevel gears instad of the 5 inner bevel gears that the new differential has. However this compatibility may unintentionally be lost as my modded version is developed.

Today I am building the original set with real bricks then seeing how I can add my mods to it.

right, that's what i thought - the new differentials are in the unofficial part database for LDCad actually ;)

can you share the full LDCAD file of the original model or is it a no-go ?

Edit: is there any specific reason you are using the small turntable to connect the drivetrain frames ?

No, I am finalising instructions for the CLAAS Scorpion telehandler, 42108 mod is next on the list.

Great, i cant wait, i mostly wonder how you worked the steering around the outriggers in the front - i got the back mostly figured out and parts are on their way but i am baffled how to handle the front part (meaning, the steering gears are in the way)

Yeah I literally fitted the 7L gear racks just now and forgot that the darn mini turntables would get in the way of the steering axle. The steering axle cant go up any further either so im in a very deep hole now and am trying to think of a fix.

The mini turntables allow for the pendular suspention whilst supporting the axles. I just don't believe LEGO sometimes!

Original model is to boring for playing. don’t have fake engine, latch mechanism is bad.
So I trying to improve those.
Function
Chassis - finish
V6 engine and differential in third axle
HOG steering moved to back of chassis
Original HOG change to release front outrigger
Crane
Remove blue 20t gear from end of boom
Remove all latch mechanism and change to distribution gearbox
Winch and boom extension now using worm gear

Interesting! I just got this model and I'm not really an experienced modder. I was thinking of using the left HOG knob to release both front and back outriggers, not sure how would I do that though. I also find the outriggers really bad at holding the crane in place, so I would like to review those as well.

I like what you did on the boom with the worm gear, quite clever! Did you just lowered the axle or added an extra layer of bricks to bring the serrated lane?

I have modified the outriggers:

Hi there! I saw your post and I believe your Rebricable instructions. However, I'm working with very, very limited availability of pieces. My childhood Legos got burnt in a house fire quite a few years ago, and I was able to salvage about 30% of them. 42108 is my very first set in about 20 years, so I still have a lot of catching up to do.

I'm debating whether to get either 42097 or 42094 as a second set to get some more pieces to work with (both of these are extremely overpriced over here, but those are the sets available in the local market, so there is that).

Anyways, that said I do love what you did with the outriggers! But for now, I guess my first step will be to make all four of them deploy at once. That should be challenging enough for someone that has been away from the Lego world for over 20 years! Thanks!

I have just finished B model for this set, DAF CF-like truck, made only with pieces from 42108 set. It comes with HoG steering on front axles (with working steering wheel), liftable container sliding frame and winch with lock. Can work also as a regular #dumptruck
I tried to add as many details as possible within given range of parts. Truck comes with detailed exterior, doors can be opened too.
